IRS-P1 or IRS-1E was an experimental earth observation mission undertaken by Indian Space Research Organisation (ISRO). The objective of the mission was to develop earth imagery using instruments carried on board. Due to a malfunction in the last stage of the rocket, the satellite deviated from its path and plunged into the sea.
IRS-P1 was a follow-up mission to the satellite IRS-1A, to develop India's capability in the field of remote sensing. The satellite was to take up missions in the area of ground-water exploration, land use, forest and flood mapping. The letter 'P' in the Indian Remote Sensing series of Earth Observation satellites indicates that the satellite was to be launched aboard a Polar Satellite Launch Vehicle (PSLV). It was launched on September 20, 1993.
IRS-P1 carried two payloads:
- LISS-I (Linear Imaging Self-Scanning System)
- MEOSS (Monocular Electro-Optical Stereo Scanner)
IRS-P1 mission was a failure, as the last stage of the PSLV-D1 malfunctioned, so failed to launch the satellite into its desired orbit.
